Freshwater fish fauna of Krishna River, Sangli district was studied from 2013 to 2017. A total of 73 species belonging to 10 orders, 22 families, and 49 genera were recorded, of which, 29 species are endemic to the Western Ghats and 11 species endemic to the Krishna River system. Labeo kontius, an endemic barb of the Cauvery River System was recorded for the first time from the Krishna River, Maharashtra. As per the IUCN Red List of Threatened Species, 54 species are assessed as ‘Least Concern’, four species as ‘Near Threatened’, three species as ‘Vulnerable’, five as ‘Endangered’, and two as ‘Data Deficient’. The conservation status of two species has not yet been assessed. Fish fauna of the Krishna River within the study area is threatened as a result of alien species, and several anthropogenic stressors such as pollution from industrial as well as agricultural sources, human settlements, and overfishing.  Since, this small study area harbours 28 endemic and eight threatened species, their conservation should be given high priority.

The freshwater fish fauna of Hiranyakeshi River, a tributary of the Krishna River System, originating in the Western Ghats of Maharashtra, was studied for a period of three years from 2013–2016.  We reported 57 species belonging to seven orders, 17 families and 42 genera.  Cypriniformes was the most species rich order followed by Siluriformes, while Cyprinidae was the most predominant family.  At least 21 freshwater fish species found in Hiranyakeshi River are endemic to river systems originating from the Western Ghats, while nine species are endemic to the Krishna River system.  The true diversity of freshwater fishes in this region, however, is still obscure because of lack of detailed taxonomic studies in this region.  Of the total species, at least 11 are in the threatened and near threatened categories of the IUCN Red List and Hiranyakeshi River holds a good population of most of these species.  The fish fauna in this region, however, is threatened by several stressors including invasive fishing practices, water impediment due to upcoming dams, invasive introduced species and water pollution due to agricultural runoffs and industrial effluents.

AbstractIUCN Red List assessments for fish species can quickly become out of date. In recent years molecular techniques have added new ways of obtaining information about species distribution or populations. In this work, we propose the Iberian Peninsula as an example of reassessment needs in its endangered freshwater fish fauna. We compiled the list of freshwater fish species occurring in continental Spain and Portugal and examined their conservation status in global and national Red Lists. We retrieved records for these species in the Iberian Peninsula and calculated several biological indexes (richness and vulnerability indexes). Our results showed a patchy data coverage of fish records in the Iberian Peninsula. Threat levels reported within national Red Lists are higher than their global counterparts, reinforcing the necessity of improving and maintaining up to date national Red Lists. Iberian watersheds have moderate levels of threat and high levels of out of date assessments. The nearly fully completed genetic databases for Iberian fish species, along with the limited distribution of many endangered species and the necessity of update their assessments constitute an excellent opportunity to use data obtained from eDNA to improve species monitoring practices and their conservation status.

Abstract Few marine taxa have been comprehensively assessed for their conservation status, despite heavy pressures from fishing, habitat degradation and climate change. Here we report on the first global assessment of extinction risk for 300 species of syngnathiform fishes known as of 2017, using the IUCN Red List criteria. This order of bony teleosts is dominated by seahorses, pipefishes and seadragons (family Syngnathidae). It also includes trumpetfishes (Aulostomidae), shrimpfishes (Centriscidae), cornetfishes (Fistulariidae) and ghost pipefishes (Solenostomidae). At least 6% are threatened, but data suggest a mid-point estimate of 7.9% and an upper bound of 38%. Most of the threatened species are seahorses (Hippocampus spp.: 14/42 species, with an additional 17 that are Data Deficient) or freshwater pipefishes of the genus Microphis (2/18 species, with seven additional that are Data Deficient). Two species are Near Threatened. Nearly one-third of syngnathiformes (97 species) are Data Deficient and could potentially be threatened, requiring further field research and evaluation. Most species (61%) were, however, evaluated as Least Concern. Primary threats to syngnathids are (1) overexploitation, primarily by non-selective fisheries, for which most assessments were determined by criterion A (Hippocampus) and/or (2) habitat loss and degradation, for which assessments were determined by criterion B (Microphis and some Hippocampus). Threatened species occurred in most regions but more are found in East and South-east Asia and in South African estuaries. Vital conservation action for syngnathids, including constraining fisheries, particularly non-selective extraction, and habitat protection and rehabilitation, will benefit many other aquatic species.

Abstract: We introduce the work providing a synthetic description of the diversity and phyletic structure of freshwater fish in the Neotropical Region, especially emphasizing that of Brazil. This is accompanied by a discussion about environments of fish from small to medium sized to large, taking into account how it shaped their respective biologies/ecologies, as well as what they imply for their use by humans. We present, as figures, the results of our exploratory analysis of Brazilian Red Book of Threatened Species of Fauna (2018), focusing on the small-sized ones, with up to 15 cm of standard length. We continue to present the main human impacts in small fish environments, along with those suffered by medium to large fish environments, and then follow by their respective deleterious effects. Finally, we present a general synthesis, reinforcing the enormous importance of small fish conservation and their respective preferred environments, followed by our main conclusions, and possible conservation strategies.

Diversity, potentiality and conservation status of fish fauna in upper Mahakam’s tributaries of east Kalimantan is unknown. The purposes of this study were to analysis species diversity, determine potentiality and conservation status of fish fauna in upper Mahakam’s tributaries, east Kalimantan. Fish sampling with purposive method was conducted in four tributaries, i.e Tepai River, Pahangai River, Danum Parai River, and Meraseh River for one month. Fishes were collected by several gears type. The results of this research showed that the total number of fish caught was 820 individuals; consist of 26 species, 7 families, and 4 orders. The Cyprinidae was the most dominant family found in all tributaries. The Shannon-Wiener diversity index in four tributaries were varied and ranging from 1.749-2.087. The highest fish diversity was recorded at Maraseh River followed by Pahangai River, Danum Parai River, and Tepai River. The low fish diversity was discovered at Tepai River may be due to differences in substrate type, water velocity, and water depth as compared to the Maraseh River, Pahangai River, Danum Parai River. The fish species similarity coefficient between four tributaries ranged from 0.606-0.842 and the highest dissimilarity was found between Tepai River and Danum Parai River. Almost all fishes categorized as edible fish for local consumption. Syncrossus hymenophysa and Gastromyzon lepidogaster have potential as ornamental fish. Regarding IUCN red list status, six fish species were grouped into least concern status, two species as data deficient, one species as near threatened, one species as endangered species and 16 other species were not on the list.

Sarcoglanidinae and Glanapteryginae catfishes are among the most unusual elements of the Neotropical freshwater fish fauna. Microcambeva ribeirae, M. barbata and M. draco are miniaturized Sarcoglanidinae known to occur in sandy microhabitats in drainages of the Brazilian Atlantic Forest. Due to their specific habitats, specimens of Microcambeva are rare in fish collections, and new records are considered noteworthy to warrant report. Recently, specimens of this genus were newly found in the Rio Doce basin in Minas Gerais and Espírito Santo States. Such new records expand the known geographic distribution of Microcambeva. Further records of Microcambeva for Rio Peruípe in south Bahia State are also reported. Comments on the distribution of Microcambeva species along the Atlantic Forest coastal basins and suggestions on its conservation status are also offered.

A total of 230 taxa of lichenized fungi are reported from epiphytic habitats in Armenia based on field studies from 2011 to 2015 and evaluation of the available literature. For each species, notes on taxonomy, chemistry, ecology, and local, regional and world distribution are presented, as well as presence in the protected areas of the country. An identification key for all species is added. Of the total, 219 are specialized epiphytes, rarely found on other substrates, while 11 species occur only incidentally on bark and more usually on rock. The epiphytic lichenized fungi of Armenia belong to 13 orders, 34 families and 88 genera. The most species-rich higher taxa are Lecanorales (Parmeliaceae, Physciaceae, Teloschistaceae), Arthoniales, Peltigerales and Pertusariales. Lecanora, Usnea and Phaeophyscia are the most species-rich genera. The following 28 taxa are new records for Armenia: Arthonia atra, Bacidia biatorina, Bacidina adastra, Biatora longispora, Bryoria fuscescens, Bryostigma muscigenum, Buellia erubescens, Candelariella efflorescens, Flavoparmelia soredians, Hypocenomyce scalaris, Lecidella cf. pulveracea, Lepraria jackii, Lepraria leuckertiana, Leptogium cyanescens, Ochrolechia pallescens, Pertusaria slesvicensis, Phaeophyscia endophoenicea, Phlyctis agelaea, Phlyctis argena, Placynthiella icmalea, Pyrrhospora quernea, Ramalina panizzei, Rinodina griseosoralifera, Rinodina polysporoides, Strigula stigmatella, Varicellaria hemisphaerica. Four genera are for the first time reported for the country, Hypocenomyce, Phlyctis, Pyrrhospora and Strigula. 188 species (82% of the epiphytic lichen mycobiota) were found in the Specially Protected Nature Areas of Armenia. The conservation status of 74 species has been evaluated following the IUCN Red List of Threatened Species categories and criteria. Among them we assessed 9 taxa as Critically Endangered, 5 taxa as Endangered, 2 taxa as Vulnerable, 4 taxa as Data Deficient and 54 taxa as Least Concern. Epiphytic lichens reported from Armenia showed predominantly holarctic distributional patterns. 187 species were found in the temperate deciduous and mixed forests, which dominate in Northern and Central Armenia, and 56 species in the open arid woodlands of Southern Armenia.
